UNITED STATES JOHN GILSENAN, OF NEW YORK, N. Y.Y

NOZZLE.

Application filed october 17, 1921. Serial No. 508,283.

To all whom t may concern: A

Be it known that I, JOHN GiLsENAN, a citizen of the United States, and aresident of New York, county of )New York, and State of New York, haveinvented certain new and useful Improvements in Nozzles, of which thefollowing is a specification.

This invention relates to an improved nozzle whichris adapted to be usedin locations where it is either impossible for firemen to remain, orwhere it is only necessary to install a pipe for wetting down purposes,and is designed to be caught over a window sill, elevator openings,cellar openings and similar situations, and is `securely held inposition, such holding being made secure when water under pressure isgoing through the hose.

The invention is illustrated in the ac companying drawing, Vin whichFigure 1 is a side view of the device, showing part of a wall and awindow opening. Figure 2 is a front view of the nozzle shown in Figure1, and Figure 3 is a side view of the top part of a modified form ofconstruction, a part thereof being shown in section.

The whole device takes on the general form ofan L-shaped structure, andI provide a pipe 10 which is bent, being bent substantially at a rightangle so that the long arm 11 and the short arm 12 are provided, thelong arm 11 having on its bottom a suitable coupling member 12 so thatan ordinary hose line 13 can be coupled thereto, the short arm 12 havingat its end means for Vseouring'it to an outlet pipe or nozzle 15 whichcan be secured thereto in any of the usual ways, usually by screwingit,on, so

, that different forms and sizes can be placed on the end of the bentpipe.

A hook 16 is provided, this usually being n formed by bending the end ofa plate- 17,

the plate 17 being secur-ed to the short arm 12 in any suitable wausually by means of collars 18 or the like, and I prefer also to bendthe endV of the plate, as at 19, to form a support for the elbow of thepipe 10, and I place a pollar 20 or its equivalent at the extremity ofthe plate to grasp and hold the pipe 10.

In'many lire situations, very often on re escapes and also on straightwalls where ladders have been raised, firemen can not remain on accountof dense .smoke or llames bursting from windows, and it is necessary todirect water through such window openings and on to the lire. In suchcases the pipe 10 is taken up to the place where it is to be installed,for instance, overa window sill into a window opening, and the length ofthe pipe 10 is suiiicientso that a fireman ata considerable distancebelow the window can hook the upper end of thedevice over the sill tothe position shown in full lines in Figure 1. The hose 13, if notpreviously attached, can now be secured in place and then the water isturned on.

When pressure is applied, by reason of the waterpassing through thepipe, very often a Vhigh pressure, the device is more securely locked inposition andv steadied, since the lower end of the long arm 11 of thepipe kicks in, as at 21, and bears against the outer side oi' the wall,and the back pressure on the short arm 12 causes the hook 16 to be moretightly pushed against the inner tace of the wall 22 below the windowopening.

If desired, the direction or" the stream can be slightly altered bygrasping the lower end Voi the long arm of th-e pipe, or by means ot thehose 13, and the pipe can be swung to a limited extent laterally and toaV con` siderab-le extent from the outer face of the wall so as todirect the stream of water from the outlet pipe in diierent directionswith in the building.

This description of the use of the pipe in a window opening is, simplyfor the purpose of making clear how it operates, and it will beunderstood that the device can be used with the long arm of the pipehorizontal, such as through a side wall, vaultlike, or through openingsout in floors leading into cellars, and by means of a suitable nozzle,such asthe so-called goose neck nozzle 23, shown in Figure 3, ahorizontal stream can be delivered from this horizontal situation of thelong arm 11 of the pipe.

If a moreflexible use of the pipe, and consequently the nozzle, isdesired, I may provide the plate 17 and the short arm 12 of the pipewith coacting means for securing such flexibility, and in the drawing Ishow a ball 24 seated inthe socket 25, and a suitable regulating nut 26can be used to enclose the ball and either lock it in position or loosenit sufficiently to permit its being rocked,

and in this wayV the hook 16 is not disturbed from its position when itis caught over the edge of :in opening, but the pipe 'lf/ can be'ont-letrpipe, seid outlet pipe (T h erin substantially et right anglesto each swung in different directions by the above described ball joint.

The pipe is adapted for use in dangerous situations, Vfor instance, ingrain elevators, where oaveins would i'reertons oi'? grain :ind Crushpeople working in 'the building, :ind such pipe can be installed in anopening in such grain elevators, and by ineens oi a ,goose neck nozzle28, :is shown in Figure Ahe stream eenA be directed vertically into suchelevators or the shafts thereof, as will be evident.

I Claim:

A nozzleeoinprisingr portable rigid reason of substantially7 right-angled pipefahook on4 the inner side ofV one of its airins, :ind :in and the end or'thereon having the erin which has the hooi:
